Current report

Ongoing conflicts and geopolitical tensions in the Middle East have contributed to macro-economic pressures in certain regions in which we operate. These developments have adversely impacted market demand and Net sales in certain markets and have also contributed to certain material and supply chain cost increases and logistics network inefficiencies. To date, these developments have not had a material impact on our results of operations. We continue to monitor developments and take actions to mitigate impacts to our business and our customers.

Previous wording

During 2025, the United States announced changes to U.S. trade policy, including increasing tariffs on imports, in some cases significantly, and potentially negotiating or terminating existing trade agreements. The United States also indicated that tariffs may change and that additional measures are under consideration to be introduced. These tariff and tariff-related measures include potential impacts to the industry in which we operate and the commodities to which our products are exposed. These actions, along with corresponding retaliatory tariffs imposed by other countries on U.S. exports, have led to significant volatility and uncertainty in global demand in both aftermarket and first-fit. In response to these developments, we mitigated the cost impact on our business by employing the exemptions for which we were eligible, such as compliance under the United States-Mexico-Canada Agreement (“USMCA”), adjusting our supply chain, and implementing select price adjustments. In February of 2026, the U.S. Supreme Court held that tariffs imposed pursuant to the International Emergency Economic Powers Act (“IEEPA”) exceeded the statutory authority granted under that law. The ruling, however, did not address the timing, availability or extent of any refunds of previously paid tariffs. On March 4, 2026, the Court of International Trade ordered U.S. Customs and Border Protection to begin the refund process for all importers who were subject to IEEPA duties.

Previous wording

The ultimate outcome, timing and amount of any refund claims remain highly uncertain, and our ability to estimate the potential impact of tariffs and related trade policy developments is limited by the continually evolving tariff and trade policy environment. During the three and six months ended June 30, 2026, we received an immaterial amount of refunds related to IEEPA duties. We continue to evaluate the potential treatment of such refunds, including whether any portion should be returned to customers under applicable contractual terms and commercial arrangements. To the extent any such amounts are returned to customers, they could negatively impact revenue in the period recognized; however, based on information currently available, we expect the net impact on EBITDA to be substantially neutral. We will continue to monitor tariff and trade policy developments and evaluate opportunities to mitigate the impact of tariffs on our business, consolidated results of operations and financial condition.

Current wording

During the three and nine months ended September 30, 2026, we received an immaterial amount of refunds related to IEEPA duties. Under applicable contractual terms and commercial arrangements, substantially all of the refunds received will be returned to customers, with the amounts retained primarily offsetting fees and other impacts. Accordingly, the net impact of the IEEPA duty refunds was not material to our consolidated results of operations, cash flows or financial condition. We will continue to monitor tariff and trade policy developments and evaluate opportunities to mitigate the impact of tariffs on our business, consolidated results of operations and financial condition.

Stabilization is expected to continue through the latter portion of 2026.

We have experienced general variability in direct material costs through the first six months of 2026, and various key commodities have been exposed to inflationary pressures.

Previous wording

In the historical periods following the Separation until the ending of the transition services agreement with Cummins in September 2025, we incurred additional costs associated with becoming a standalone public company. These expenses and capital expenditures primarily relate to the establishment of functions previously co-mingled with Cummins, such as information technologies, distribution centers, manufacturing and human resources. Under the transition services agreement, Cummins continued to provide certain services related primarily to administrative services. With the conclusion of this agreement, we do not expect to incur any additional one-time expenses or capital expenditures in 2026 or any future periods in connection with becoming a standalone public company.

Accounting for acquisitions requires Atmus to recognize separately from goodwill the assets acquired and liabilities assumed at their acquisition date fair values. Goodwill is measured as the excess of the purchase price over the net amount allocated to the identifiable assets acquired and liabilities assumed. While management uses its best estimates and assumption to accurately value assets acquired and liabilities assumed at the acquisition date, the estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, Atmus may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. The operating results generated by the acquired businesses are included in the Condensed Consolidated Statements of Net Income from their respective dates of acquisition. Acquisition related costs are expensed as incurred. See Note 2, Acquisitions for additional information.
